A robust self-scheduled missile autopilot:: design by multi-model eigenstructure assignment

This paper describes the synthesis of a self-scheduled controller robust with respect to parametric uncertainties. Traditionally, scheduling is done a posteriori by interpolation of gains computed for several points within the parameter space. The method proposed here. named (Mu-mu)-iteration, is based on worst-case analysis and multi-model eigenstructure assignment. It permits the designer to synthesize a robust low order controller by considering a priori its dependence of some scheduling parameters. The method is then applied to derive a robust missile autopilot. (C) 2001 Elsevier Science Ltd. All rights reserved.
